how much i want to see Tom同位语从句,是idea的同位语.You really have no idea how much I want to see Tom这里have no idea 是don't know 的意思，那么，how much I want to see Tom 是宾语从句了。You really don't havethe idea ... 是否等于You really have no idea ...呢？how much .... 后面是否接的是否是宾语从句呢？You really don't havethe idea ... 是否等于You really have no idea ...have no idea 是don't know 的意思 。但是have no idea 并不是don't knowdon't know 后面是宾语从句， 而have no idea 就是同位语从句请采纳！你的意思是说：虽然have no idea 含义上等同于don't know, 但是后面接的从句称呼是不一样的。是吗？别忙要采纳，我问清楚了，一定我会给的。而且追加10分虽然have no idea 含义上等同于don't know, 但是后面接的从句称呼是不一样的。
